Later, if the script runs against another new ticket, but a match is found and the new ticket is merged under the existing ticket, this is the History entry on the existing ticket:

And all of that makes sense as well - except why it references my name. I assumed it was because I entered the script into Zoho and that didn't matter to me. But now I suspect that, because the platform thinks that it's ME running the script to "markAsUnRead" then that result only applies to ME.
I'm just delving into Deluge and by no means have more than a superficial understanding, but this is something we really need resolved - and honestly seems like it should be an easy fix - so any help is much appreciated.
